摘要

本工作提出了一种基于分形几何的频率选择表面(FSS)用于雷达系统应用。采用Sierpinski曲线的第三次迭代来设计FSS。Sierpinski曲线具有空间填充特性，可使FSS小型化。该器件在1.82 GHz和4.79 GHz处具有双极化特性和双阻带响应，适用于干扰保护应用。L和C波段的信号被过滤，避免了最终对S波段频率的相邻干扰。此外，还对不同极化波入射进行了研究。利用ANSYS HFSS软件进行频率响应仿真。为了验证，给出了仿真和测量结果并进行了比较。

A New Design of Sierpinski Curve Fractal FSS for S-band Interference Protection Applications

This work presents a Frequency Selective Surface (FSS) based on a fractal geometry for radar systems applications. The third iteration of Sierpinski curve is used to design the FSS. The Sierpinski curve has a space-filling propriety to miniaturize the FSS. The device presents a dualpolarized behavior and two stop-band response at 1.82 GHz and 4.79 GHz, which are suitable for interference protection applications. The L and C bands signals are filtered avoiding eventual adjacent interference to S band frequency. Additionally, an investigation is performed for different polarized wave incidence. The simulation frequency responses are performed using ANSYS HFSS software. The simulation and measurement results are shown and compared for validation purposes.
